Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Ramda: A practical functional library for JavaScript programmers
I find straight forward, dedicated combinators much more readable and practical to use ie. for iterables (context where it makes a lot of sense) [0] example [1], runtime assertions (through refutations, which are much faster than combinators over assertions) [2], parser combinators for smallish grammars [3] etc.
In many cases vanilla/imperative js is more readable and terse, no need to bring functional fanaticism everywhere, just in places where it gives true benefits and in form that can be understood by peers.
Functional code can be beautiful and can also be unreadable/undebugable. Same with imperative code. It's great in js/ts you can pick approach where the problem is expressed more naturally and mix it at will.

Loopless Code
Loops are great if your programming languages supports iterables/iterators/generators (also async generators) like in js/ts for example.
Especially generator-to-generator combinators ie. [0] give you terse, transducer expressiveness over computation on finite/infinite streams, arrays, etc. (all iterables). It's easy to compose them, jump into for loops if needed for arbitrary yielding (ie. yielding multiple items sometimes, skipping some, halting etc). `continue`, `break`, nesting, yield, yield from, normal code in for loops is very intuitive and terse creating pleasant, understandable code.

Pipe Operator (|>) For JavaScript
There was also a different proposal that allows objects to be extended: https://github.com/tc39/proposal-bind-operator
Personally, I don't use classes much, but sometimes I think free functions a little bit hard to find, so I tend to experiment with the following pattern.
interface User { … }
const User = {

JavaScript tutorials
In modern JS, you can export each function directly without putting them in an object. It also allows you to call a function with a specific “this” value, function.bind(object)(args). As a matter of fact, there’s a syntax proposal proposal and to do exactly this, object::function(args). This proposal could make what you describe pretty popular.
